A) lateral orbital margin to the lateral cranial cortex on the left side than on the right side.
B) crista galli to the lateral cranial cortex on the right side than on the left side.
C) right mandibular ramus to the cervical vertebrae than from the left mandibular ramus to the cervical vertebrae.
D) lateral orbital margin to the lateral cranial cortex on the right side than on the left side.

Question

Quizplus · Accepted Answer

When the patient's face is rotated toward the right side during a PA cranial projection, structures on the side away from the rotation (left side in this case) will appear farther from the midline structures compared to the side of the rotation. Therefore, the distance from the lateral orbital margin to the lateral cranial cortex on the left side will appear greater than on the right side.
